How to detect someone's stealing CPU's resources or NAS's movies?

in flag

I noticed my NAS LAN LED's activity is always blinking, moreover today I used Windows and I realized that the fan noise was much much quieter than in Ubuntu. Of course this can be due to the fact I'm running many services in linux <paranoic_mode> but it can be somebody is stealing my resources. </paranoic_mode>?

In particular do you know what is unn-143-244-37-89-datapacket? I saw a huge amount of data from my PC (lello) and that address.

@ChanganAuto Thanks. I got that almost one is malicious so now 1) how to get rid of it? 2) How to prevent that to happen again?

Without the VPN the situation is even worse: [EtherApe screenshot](https://drive.google.com/file/d/1TiukO5TW-NT-p_qRie8PZuHSJfAQ7QLd/view?usp=sharing)

I started suspecting that the NAS' LAN LED fast blinking is due to high traffic volume in the LAN. I found a [post](https://askubuntu.com/questions/917825/etherape-shows-a-huge-number-of-nodes-from-my-computer) that is almost the same but, sadly, hasn't any solution.

That second etherape screenshot is full of ICMP pings, so either your router is configured to allow direct ICMP to that machine or it is doing some scanning.

I just checked: my router doesn't mention "ICMP". How can I block all of that non wanted traffic?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
